Signal Averager

This document serves as a user manual for the PDP-12 Signal Averager, a program designed to digitize, display, and average analog signals at rates ranging from 55 to 4095 microseconds per point per channel.

Key aspects of the document include:

• System Requirements: The program requires a PDP-12A computer with 4K of core memory, a KW12A clock, and a LAP6-DIAL system tape.
• Operations: It provides detailed instructions on how to load the program via the DIAL loader, connect experimental leads, and configure settings like sampling rates, number of sweeps, and delays using the Teletype.
• Features: The manual covers advanced operations such as pausing, clearing accumulated data, switching between view modes, expanding/contracting viewing scales, plotting data to an X-Y recorder, and typing output to a Teletype.
• LINCtape Functionality: It explains how to store averaged results on LINCtape for later retrieval.
• Customization: A significant portion (Appendix A) is dedicated to advanced users, detailing how to modify the source code, adjust job lists, change channel display lists, and configure the program for specific experimental needs using the DIAL Editor and Assembler.
• Reference: The guide concludes with a comprehensive list of Teletype commands and a full assembly listing of the program source code.
